SPECIFICATION forming part of Letters Patent No. 589,890, datedSeptember 14, 1897.

' Application filed January 2, 1897. Serial No. 617,835. (No modehl TctZZ whom it may concern:

Be it known that I, GEORGE BINOKLEY, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have in vented certain new and useful Improvements inHand-Levers; and I do hereby declare that'the followingis a full, clear,and exact description thereof.

The present invention relates to certain new and useful improvements inhand-levers for operating and controlling mechanical devices, whichconsists in the arrangement of parts and details of construction, aswill be hereinafter fully set forth in the drawings, and described andpointed out in the specification.

The object of the invention is to so coustruet the hand-lever and itsconnections that entirely separateand distinct trains of mechanism maybe operated and controlled by a single hand-lever-as, forinstance, tocontrol the opening and the closing of a throttlevalve and the mechanismfor starting and reversing an engine, thus enabling; theuse of one leverto perform the work ordinarily rcquired of two or more levers, and henceere: ating a saving not only in the expense of a number of the levers,but a V saving of time and a saving of annoyance and possibleconfusionof the operator by being compelled to handle a series oflevers. Y

In order to fully understand the invention, reference mustbe had to theaccompanying sheet of drawings, forniing a part of this application,whereint Figure 1 is aside view inelevation, showing the hand-lever and.its lconnecting mechanism. Fig. 2 is an end view in elevation of themechanism illustrated by Fig. 1. Fig. 3 is a top plan view taken on linem 00, Fig. 1; and Fig. 4 is a similar view taken below the floor-line. Q

I11 the drawings the letter A is used to indicate the floor orbase-plate, and A is used to indicate thehand -lever, which extendsthrough an elongated opening a, cut within the floor or'baseplate A.This lever at its lower end terminates in or is provided with a jaw a,which jaw embraces and is secured to the shaft A by the bolt 13. Thebolt B passes through the sides of the jaw a and through the shaft A ata right angle to its means, such as short standards B The quadrant-barsare placed such a distance apart as to permit lateral or side movementto the hand-lever as thrown over upon its fulcrumed point.

In order to provide against accidental side movement or playto thehandlever, a vertically-movable catch or latch d is secured to each facethereof, which catch or latchis connected to the hand-lever D, fulcrumedto the lever A near its upper. end by the connecting-rod D. The catchesor latches cl embrace the outer face of each quadrant h b and act 'orserve as guides for holding the hand-lever against lateral or sidemovement or play, although they permit of free forward or backwardmovement being given to the hand-lever for the reason that they slideupon the face of the quadrants, unless notches be provided in the faceof the quadrants, into which the catches or latches fit, in which caseit would be necessary to raise the catches from within thequadrant-notches before the hand-lever be thrown forward or backward. Itwill thus be observed that while the hand lever isfree to be thrownforward and backward in the position illustrated by dotted lines inFig.;l;in orderfto Toscillate the shaft A it is held locked against sideor lateral movement.

This oscillatory shaft A is connected in any suitable manner say withthe throttle-valve mechanism of an engine. (Connection not being shown.)Consequently as the hand-lever is thrown backward or forward the saidshaft. will be oscillated so as to control the movement of thethrottle-valve.

Below the floor or base A is suspended, by brackets D D the yoke O thetrunnions d d of the yoke workiiig'in bearings e of "the brackets. Thecenters of these trunnions are in axial line with the axis of the shaftA Between the horns of this yoke C are suspended the secondary quadrantsE E, which quadrants are secured by bolts 6 to the end blocks E Thes'eend blocks are provided with trunnions f, which work in bearings f inthe horns of the yoke O. The secondary quadrant E is provided with alaterally-projecting arm F, which arm has cut therein, near its outerend, the curved slot g. ithin this slot is fitted a pin g, which issecured to a stud g downwardly projecting from the floor or base-plate.This pin, fitting within the curved slot, holds the arm 1 and theswinging secondary quadrants at all times and under all conditions in ahorizontal plane, whatever position the yoke C may assume, and causesthe swinging quadrants to move along in the direction of the axis of theshaft A The hand-lever A extends upwardly between the secondaryquadrants E E, and it is provided, at a point between the saidquadrants, with a spherical-ended pin h, composed of steel or othersuitable material, the ends of which pin fit within the socket cut inthe inner face of the disks E E which disks are so fitted between thesecondary quadrants E E that the outer face thereof will slide along theinner face of the said quadrants as the hand-lever is thrown forward orbackward.

The end of trunnion d of the yoke G extends beyond the bearing ofbracket D and has keyed or otherwise secured thereon the collar G, whichcollar is provided with an outwardly-extending arm G. This arm connectswith any suitable line of mechanism, (not shown,) as the reversingmechanism of an engine, so that as the said arm is thrown up or down themechanism controlled thereby will be suitably operated.

In order to operate the line of machinery controlled by the movement ofthe shaft A the hand-lever A is thrown either forward or backward, so asto cause the jaw end of the lever to oscillate the shaft A in thedesired direction. The hand-lever as thrown to es cillate the shaft Awill not move or swing the yoke C, for the reason that the said levermoves between the secondary quadrants. If it is desired to operate theline of machinery controlled by the movement of the arm G, it isnecessary that the hand-lever D be first pressed inward, which, throughits connections, raises the catches or latches 61, so as to clear thequadrants b l). The hand-lever is then thrown laterally or to one sidein line with the axis of the shaft A which, as moved over, causes theyoke C to swing in its bearings by the lever drawing upon the swingingquadrants E E. As thrown laterally the hand-lever turns upon itsfulcrumed point. Consequently the shaft A remains undisturbed. Duringthe throw of the yoke C the trunnion d is turned so as to raise or lowerthe arm G in order to operate the line of machinery controlled thereby.By simply throwing the hand-lever forward or backward at a graduallateral incline both lines of mechanism may be set in operation by onethrow of the hand-lever. It will thus be observed that each line ofmachinery may be operated independently, or both may be controlled byone movement of the hand-lever.

IIavin g thus described my invention, what I claim as new, and desire tosecure protection in by Letters Patent, is

1. The combination in a lever mechanism, of a hand-lever, a jaw formedon the lower end thereof, which embraces an oscillatory shaftcontrolling a train of mechanism, a bolt passing through the jaw andoscillatory shaft and forming a fulcrumed point for the hand-lever, atright angles to the axis of the shaft, the fixed quadrants between whichthe handlever works, the latch or catch movably connected to thehand-lever and arranged to engage the quadrants, the swinging orsecondary quadrants secured between the horns of a swinging yoke whichis thrown by the lateral throw of the hand-lever, and of connectionbetween the swinging yoke and an independ ent train of mechanism fromthat controlled by the oscillatory shaft.

2. The combination with the hand-lever, of an oscillatory shaft to whichthe hand-lever is fulcrumed at right angles to its axis, said shaftbeing connected to one train of mechanism, the quadrant-bars betweenwhich the hand-lever works, a movable latch or catch carried at eachside of the hand-lever which engages the quadrantbars, the secondaryquadrants suspended between the horns of a swinging yoke, the disksarranged between the swinging quadrants and held in place by aspherical-ended pin passing through the hand-lever, and of suitableconnection between the swinging yoke aud a second train of mechanism.

3. In a lever mechanism, the combination with the oscillatory shaftconnected to a train of mechanism, of a hand-lever fulcrumed to theshaft at right angles to its axis, the fixed quadrants between which thehand-lever works, a movable latch carried at each side of said leverwhich embraces the sides of the fixed quadrants, the swinging yokeconnected to a second train of mechanism, the secondary quadrantssuspended between the horns of the swinging yoke, the sliding disksarranged between said quadrants and held in place by means of aspherical ended pin passing through the hand-lever, an arm having a slotcut in its outer end portion projecting from one of the suspendedquadrants and a pin working in the slotted end portion of the arm andserving to hold the arm and suspended quadrants in a horizontal planeduring the movement of the swinging yoke.

In testimony whereof I affix my signature in presence of two witnesses,this 26th day of December, 1896.
